The Lowdown
Alright, let’s break it down for Kennebunk Beach. This 16-day window looks pretty grim for a proper session. We’ve got a long stretch of small, messy, or blown-out surf, so don’t get your hopes up.
It starts Saturday the 18th with a chest-high pulse at around 6ft from the south, but the period is a short 6 seconds. Wind is honkin’ from the SSW at 15 mph, making it cross-on and choppy. The combined energy is moderate (204), but it’s just a mess.
Sunday the 19th drops off hard. You’re lookin’ at knee-to-waist-high slop – 2ft in the morning, down to 2ft in the arvo – with a 6-second period. Wind goes northwest at 12 mph, but it’s still cross-shore and choppy. Weak energy.
Monday the 20th through Wednesday the 22nd is a total washout. Tiny, weak swell from the south to SSE, periods from 3 to 8 seconds, and onshore or cross-onshore winds keep it ugly. Wednesday the 22nd sees a bump to 7ft to 8ft from the SSE with a 7-8 second period, and the combined energy jumps to 431 and 782 (moderate to strong). But the wind is onshore from the SSW and SW at 12 mph, so the quality is poor. That kind of size with onshore wind? That’s kite-surfing territory, not paddle.
Thursday the 23rd holds around 4ft from the SSE, but again, cross-onshore winds and a short period (8-9 seconds) keep it messy. Friday the 24th morning shows the only clean-ish moment: 3ft from the ESE, 8-second period, light east wind at 3 mph, and combined energy of 165. It’s small and ordinary, but it’s clean.
Saturday the 25th through Sunday the 26th offers small waist-high waves (3ft to 3ft) from the SE with an 8-second period. Sunday morning actually goes glassy – a rare treat – but the energy is weak (92 and 88). Clean but tiny.
Monday the 27th through the end of the month and into early August, the swell stays small (2ft to 4ft) with periods of 6-8 seconds. We get some offshore winds from the NE on the 28th, which cleans things up. The standout in this whole run is Tuesday the 28th afternoon: 4ft from the east, 7-second period, offshore wind from the NE at 15 mph, and combined energy of 154. It’s not big, but it’ll be clean. Still, it’s just an “ordinary” day.
Thursday the 30th morning is the best of the bunch: 4ft from the east, 8-second period, offshore wind from the NE at 6 mph, and combined energy at 296. Clean but nothin’ special.
After that, it’s weak, small, and clean but forgettable. Saturday the 2nd of August wraps it up with tiny 2ft to 3ft waves and weak energy.
For Kennebunk Beach, this is a pretty typical quiet stretch. The water temp is about 64°F, which is average for this time of year. The break is sheltered from the ENE, so any real easterly swell with offshore north-easterly wind would be your gold, but we only get a couple of half-decent, clean moments. Keep an eye on the long-range, but don’t get too excited.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
